{"product_id":"eev-thing-founders-edition","title":"EEV Thing - Founders Edition","description":"\u003cp\u003eThe ultimate tool for diagnosing EEV motor problems on VRF and Ductless Split systems. Instead of pulling out the needle probes to take resistance readings, just connect the valve to the EEV Thing, hold down the button to scan, then press to cycle through resistances on all 4 coil windings.\u003c\/p\u003e\n\u003cp\u003eIf one of the windings has failed it can sometimes take out the control board as well. Just cut the plug end off of the failed EEV and wire it into the other side. Now you can plug the EEV thing into the control board and check that it is outputting 12VDC to every winding.\u003c\/p\u003e\n\u003cp\u003eWhile there are devices out there made to drive EEVs, the resistance of the motor windings still needed to be checked the old fashioned way. The EEV Thing is the perfect companion to an EEV driver, or as a standalone tool for diagnostics.\u003c\/p\u003e\n\u003cp\u003eWorks with 5 and 6 wire unipolar stepper motors with 2.54mm connector pitch, which covers the vast majority of EEVs in VRF equipment.\u003c\/p\u003e\n\u003cp\u003eThe Founder's Edition of the EEV Thing is my first run of boards where a significant amount of issues in my design were found and corrected. Each one has been hand modified to work as originally intended. There are 8 Founder's Edition EEV Things available and each one will be numbered x\/8 so you can own a piece of history.\u003c\/p\u003e\n\u003cp\u003eMadison Innovations is completely self-funded and the profits from the sale of the Founder's Edition EEV Things will be going towards the first production run of PCBs and get the EEV Thing in as many hands as possible.\u003c\/p\u003e\n\u003cp\u003eThe target price of the EEV Thing is going to be ~$100 when it goes on sale. Your purchase of the Founders Edition will also include a voucher for a production EEV Thing as well!\u003c\/p\u003e\n\u003cp\u003eNote: The EEV Thing name, my company logo, etc. will be engraved onto the device but I haven't finished the design yet and didn't want to delay posting the product. I will update the photos once I have some engraved. If you place your order before the photos are updated, I will send you pictures before I ship your Founder's Edition EEV Thing so you can cancel your order if you hate the design (or recommend a change that I can make so it looks better).\u003c\/p\u003e","brand":"Madison Innovations","offers":[{"title":"Default Title","offer_id":50935738957991,"sku":null,"price":150.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/4240\/5543\/files\/IMG20260628110011.jpg?v=1783193560","url":"https:\/\/madisoninnovations.com\/products\/eev-thing-founders-edition","provider":"Madison Innovations","version":"1.0","type":"link"}
